FCM：onMessageReceived未被调用，即使发送消息到fcm也没有收到通知？

javaandroidpush-notificationfirebase-cloud-messaging

我正在开发一个应用程序，希望通过php实现FCM推送通知。

因此，我创建了两个java文件： 1.FirebaseInstanceID（在数据库中正常运行并获得令牌） 2.FirebaseMessagingSerivice（未被调用）

我的FirebaseMessagingService.java

package com.example.xyz;

import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Intent;
import android.support.v4.app.NotificationCompat;
import com.google.firebase.messaging.RemoteMessage;

public class FirebaseMessagingService extends com.google.firebase.messaging.FirebaseMessagingService{

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {

    showNotification(remoteMessage.getData().get("message"));
}

private void showNotification(String message) {

    Intent i = new Intent(this,Dashboard.class);
    i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

    PendingIntent pendingIntent = PendingIntent.getActivity(this,0,i,PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
            .setAutoCancel(true)
            .setContentTitle("FCM Test")
            .setContentText(message)
            .setSmallIcon(R.drawable.common_google_signin_btn_icon_dark)
            .setContentIntent(pendingIntent);

    NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

    manager.notify(0,builder.build());
}
}

运行我的php脚本发送消息到FCM时的结果：

 {\"multicast_id\":7077449602201888040,\"success\":1,\"failure\":0,\"canonical_ids\":0,\"results\":[{\"message_id\":\"0:1465110073498648%d215149df9fd7ecd\"}]}

但是我仍然没有收到任何通知，所有配置，如 API 密钥、包名称（在 FCM 控制台中，我的项目）都已经检查过了，并且它们都是正确的。
当我在 FirebaseMessagingService.java 中的 onMessageReceived() 创建断点进行调试时，它并没有进入该方法，当消息通过 PHP 脚本推送到 FCM 服务器时，应用程序会正常运行。
我的 Dashboard.java。
public class Dashboard extends AppCompatActivity {

private Toolbar toolbar;
private DrawerLayout drawer_layout;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_dashboard);

    toolbar=(Toolbar) findViewById(R.id.app_bar);
    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayShowHomeEnabled(true);

    drawer_layout=(DrawerLayout) findViewById(R.id.drawer_layout);
    NavigationDrawerFragment drawerfragment= (NavigationDrawerFragment) getSupportFragmentManager().findFragmentById(R.id.fragment_navigation_drawer);
    drawerfragment.setUp(R.id.fragment_navigation_drawer,drawer_layout,toolbar);


    FirebaseMessaging.getInstance().subscribeToTopic("test");
    FirebaseInstanceId.getInstance().getToken();

}

但是我的仪表板活动包含一个片段。我不确定这是否会成为问题。

提前感谢您！

你是否发送到了正确的令牌？能否添加你清单文件的代码。 - Shubhank
已经添加了……是的，我发送了正确的令牌，只有这样才能从 FCM 服务器获得结果中的 success:1。请检查一下。 - Tejasv Kulshrestha
如果您将消息发送到另一个设备标记，也将成功。请卸载应用程序并重新安装以获得新的标记，并使用它来发送消息。 - Shubhank
我也做了这件事，我百分之百确定我发送到 FCM 服务器的令牌与我想要通知的设备相同...谢谢。 - Tejasv Kulshrestha
你能分享一下你正在发送的服务器端 object 吗？因为我也遇到了同样的问题。 - Usman lqbal

您没有遵循正确的代码。请再次查看此链接。 解决方案 请使用以下代码。
<action android:name="com.google.firebase.MESSAGING_EVENT" />

替代

<action android:name="com.google.firebase.MESSAGE_EVENT"/>

常见错误。
android:name="YourApplicationPackageName.YourFirebaseMessagingServiceName"

你需要更改一些部分 AndroidManifest.xml。 你的代码:
 <service
        android:name=".FirebaseMessagingService">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGE_EVENT"/>
        </intent-filter>
    </service>
    <service
        android:name=".FirebaseInstanceIDService">
        <intent-filter>
            <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
        </intent-filter>
    </service>

替换为以下代码：

用以下代码替换：

<service
            android:name="com.example.noticeboard.FirebaseMessagingService">
            <intent-filter>
                <action android:name="com.google.firebase.MESSAGE_EVENT"/>
            </intent-filter>
        </service>
        <service
            android:name="com.example.noticeboard.FirebaseInstanceIDService">
            <intent-filter>
                <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
            </intent-filter>
        </service>
最近几个小时前，我解决了这个问题，问题出在清单文件中。我只是将“com.google.firebase.MESSAGE_EVENT”更改为“com.google.firebase.MESSAGING_EVENT”..这解决了我的问题..顺便说一句，感谢你的努力！ - Tejasv Kulshrestha
我也有同样的问题，上面提到的答案对我有效。 - Usman lqbal
你改了什么？ - Usman lqbal
我刚才在评论中提到，我将“com.google.firebase.MESSAGE_EVENT”更改为“com.google.firebase.MESSAGING_EVENT”，问题得到解决！ - Tejasv Kulshrestha
